TELECOMMUNICATION NETWORK SYSTEM AND METHOD IN COMMUNICATION SERVICES USING SESSION INITIATION PROTOCOL

摘要

An implementation of a voice-over-Internet protocol (VoIP) system (200) for accomplishing two-way, three-way and conference calling between two or more parties (102) is disclosed, in which new call features (210, 220, 230) are readily adapted. The VoIP system (200) is implemented in a Session Initiation Protocol (SIP) framework in which aspects of Distributed Feature Composition (DFC) architecture are modified and applied to overcome known limitations in the adaptability of existing VoIP frameworks.
